Flow net construction
WebGraphical construction of a flow net needs to be undertaken in an isotropic material. However, a flow net can be obtained for an anisotropic material by taking the following steps: 1) transform the geometry of the system to an equivalent isotropic system; 2) draw the flow net for the isotropic system; and, 3) transform the flow net back to the ... WebThe flow net shown in Figure 10.10(a) is for a homogeneous, isotropic medium. The hydraulic heads, pressure heads, and fluid pressures (or pore pressures) that exist at any point in the system are independent of the hydraulic conductivity of the medium, although the flow velocities and quantities of leakage would of course depend on this parameter.

WebOne of the methods to estimate this quantity of water seepage is flow net. We have already discussed the method of flow net construction when the flow was confined that means all the boundary conditions of the flow were known to us. But seepage through an earth dam is the case of unconfined flow of which the upper boundary is not known. WebSeveral assumptions underlie flow net construction: 1) Two dimensional flow. This implies no recharge or discharge perpendicular to the plan of the flow net. 2) Isotropic medium. Hydraulic properties (e.g. hydraulic conductivity) are independent of the direction of measurement. 3) Steady-state flow. At a point, velocity of flow does not vary in ...
